Benefits of technology

The solution enables reduced power consumption by generating a low-frequency sync signal that matches the image type, compensating for charging period differences between data voltages of positive and negative polarities, and improving display efficiency.

Problems solved by technology

Therefore, power consumption of the LCD panel while displaying the static image may be higher than necessary.

Embodiment Construction

[0037]Hereinafter, the inventive concept will be explained in detail with reference to the accompanying drawings.

[0038]FIG. 1 is a block diagram illustrating a display apparatus according to an exemplary embodiment.

[0039]Referring to FIG. 1, the display apparatus may include a display panel 100, a panel driver 200 connected to the display panel for driving the display panel 100, and a timing controller 300 connected to the panel driver for controlling the panel driver 200.

[0040]The display panel 100 may includes a plurality of data lines DL, a plurality of gate lines GL and a plurality of sub-pixels P connected between the data and gate lines.

[0041]The data lines DL extend in a first direction D1 and are arranged in a second direction D2 crossing the first direction D1. The gate lines GL extend in the second direction D2 and are arranged in the first direction D1. Each of the sub pixels P may include a thin film transistor TR which is connected to a data line DL and a gate line GL, ...

Abstract

A display apparatus includes a mode determiner configured to compare image signals of a previous frame and a current frame and to determine an image mode of the current frame, a sync signal generator configured to generate a panel sync signal with a low frequency corresponding to the image mode using an original sync signal with a normal frequency, the low frequency being a non-divisor frequency of the normal frequency and lower than the normal frequency, a data driver configured to drive a data line of a display panel using a data sync signal based on the panel sync signal with the low frequency, and a gate driver configured to drive a gate line of the display panel using a gate sync signal based on the panel sync signal with the low frequency.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority from and the benefit of Korean Patent Application No. 10-2015-0114905 filed on Aug. 13, 2015, which is hereby incorporated by reference for all purposes as if fully set forth herein.TECHNICAL FIELD[0002]Exemplary embodiments of the inventive concept relate to a display apparatus and a method of driving the display apparatus.
